Custom Radiator Fabrication in Calgary

A custom radiator calgary is a cooling unit built from scratch to your exact specifications. Unlike standard repair work that fixes an existing radiator, custom fabrication starts with raw materials and produces a brand-new unit designed for your specific application. When factory parts are discontinued, undersized, or simply do not exist for your build, a custom-built radiator is the only reliable solution. City Wide Radiator designs and fabricates custom radiators for vehicles, industrial equipment, and specialty machinery across Calgary and Southern Alberta. Whether you need a one-off unit for a 1950s restoration or a high-capacity cooler for heavy equipment, we build it in-house from consultation through final pressure testing.

Custom Radiator Design and Engineering

Every custom radiator repair starts with precise measurements and engineering. We work directly with you to define the dimensions, cooling capacity, inlet and outlet positions, and mounting points your application requires. Our team evaluates the operating environment, expected heat load, and available space to design a unit that fits and performs from day one. For clients needing custom radiator fabrication in Calgary, we handle every stage of the design process on-site.

Our Custom Fabrication Services

We fabricate radiators using aluminum, copper, and brass depending on the application. Each unit is hand-built to match your design specifications, then pressure tested before delivery. Our shop handles everything from core assembly and header tank construction to fitting custom brackets and mounting hardware. We work with individual vehicle owners, race teams, fleet operators, and industrial contractors who need cooling solutions that off-the-shelf parts cannot provide. If you also need aluminum welding and fabrication for brackets, shrouds, or intercooler piping, we handle that under the same roof.

Custom Radiator Solutions by Application

Vintage and Classic Car Radiators

Factory radiators for pre-1980 vehicles are often unavailable or poorly reproduced. We build exact-fit replacements using original dimensions and period-correct materials, including copper and brass cores for vehicles that need to look and perform as they did when new.

Racing and Performance Radiators

High-output engines produce more heat than stock cooling systems can manage. We fabricate lightweight aluminum welding radiators with increased core thickness, higher fin density, and optimized flow paths designed for sustained high-RPM operation on the track or the drag strip.

Industrial Radiators

Generators, compressors, and stationary engines rely on radiators built to handle continuous duty cycles. We fabricate heavy-duty industrial radiators units sized for your equipment's heat output, coolant volume requirements, and physical mounting constraints.

Agricultural Equipment

Farm equipment operates in extreme dust, heat, and vibration. We build custom radiators for tractors, combines, and irrigation pumps using reinforced cores and heavy-gauge tanks that stand up to rough field conditions season after season.

Marine and Specialty Cooling

Boats, generators, and custom machinery often require non-standard radiator configurations. We fabricate marine-grade cooling units with corrosion-resistant materials and custom port layouts to match your vessel or equipment exactly.

Prototype and One-Off Builds

Building something that has never been done before? We work with fabricators, engineers, and hobbyists to produce single-run radiators for kit cars, engine swaps, custom chassis builds, and experimental equipment.

Our Custom Build Process

We follow a structured build process for every custom radiator project. This keeps timelines predictable and ensures the finished unit meets your specifications without rework. From the initial conversation to final delivery, you know exactly where your project stands at each stage. If your existing unit needs attention first, our radiator repair services can assess whether repair or full custom fabrication is the better path forward.

Consultation and Design Specs

We start by reviewing your application, taking measurements, and defining material choices, cooling targets, and connection points before any metal is cut.

Build and Pressure Test

We fabricate the core, weld headers and tanks, install fittings, and pressure test the completed unit to verify it holds under operating conditions.

Frequently Asked Questions

A custom radiator is a brand-new cooling unit built from raw materials to your exact dimensions and specifications. It is not a repaired or reconditioned existing unit. You need one when OEM replacement parts are discontinued, when your application has non-standard space or cooling requirements, or when you are building something entirely new like an engine swap or custom chassis. If a factory radiator exists and fits your needs, standard copper radiator services or repair may be more cost-effective.

We fabricate custom radiators using aluminum, copper, and brass. Aluminum is the most common choice for modern performance and industrial applications because of its strength-to-weight ratio and heat transfer properties. Copper and brass are preferred for vintage restorations and applications requiring soldered construction. We recommend the best material based on your budget, the operating environment, and whether appearance matters for the final installation.

Most custom radiator builds take between five and ten business days from design approval to completion. Simple single-core units on the shorter end, while multi-pass designs with custom brackets or unusual configurations may take longer. Rush orders are available when schedules are tight. We provide a timeline estimate during the initial consultation so you can plan around it.

We need the overall dimensions of the available space, the inlet and outlet sizes and positions, the type of vehicle or equipment, and the engine’s expected heat output. Photos of the installation area are helpful. If you are replacing an existing radiator, bringing the old unit to our shop speeds up the quoting process. Contact us with your project details and we will provide a written estimate.

Yes. Vintage and classic car radiators are one of our most common custom fabrication projects. We build exact-fit replacements using copper and brass cores with correct tank profiles, mounting holes, and hose connections for the original vehicle. Whether you are restoring a matching-numbers show car or building a restomod with a modern engine, we match the radiator to the project.
